The Metallogenetic Regularity and Prospecting Guide of Porphyry-type Cu and Au Deposits Related to Adakitic Rocks in the Central and Southern Gansu

The paper has researched the geological features,temporal-spatial distribution and tectonic evolution of mineralization of the Adakitic rocks in the central and eastern sections of Gansu Province,and in the western part of West Qinling.It analyses the porphyry-type Cu and Au deposits related to adakitic rocks,especially about the metallogenetic regulations and geological contraints,and metallogenetic model of adakite-type Cu and Au deposits,and provides a guidance and theory for Cu-Au-prospecting exploration in this area.
